Introduction
Confidential Computing Platforms are advanced security solutions designed to protect sensitive data while it is actively being processed inside cloud or on-premises environments. Traditional encryption secures information at rest or during transmission, but confidential computing adds another protection layer by isolating workloads in hardware-protected environments known as Trusted Execution Environments or secure enclaves.
As organizations move critical workloads, AI models, analytics systems, and regulated applications into cloud environments, confidential computing has become increasingly important for protecting intellectual property, financial data, healthcare records, and enterprise AI systems from insider threats and advanced cyberattacks.
Real-world use cases include:
- Secure AI model training and inference
- Financial fraud detection systems
- Healthcare analytics and genomic research
- Secure multi-party analytics collaboration
- Privacy-focused cloud computing
Evaluation Criteria for Buyers
